Whether this much richness is right for you depends on your strand thickness, porosity, and how easily your hair flattens — that is what the consultation works out.

What the formula actually does

Read from the label, not the marketing

Each row says where it comes from: F means we derived it from this product’s own ingredient list, S means it is a claim the brand makes that the formula neither confirms nor contradicts.

Slip and detangling High

Conditioning agents sit high in the list — this is a detangling formula.

Oils and butters Present, high in the list

Oils sit high in the list — a softening, coating formula.

Weight on the hair Medium

Middle of the range — noticeable on fine hair, light on coarse hair.

Water-binding (humectants) Low

Humectants appear, but low enough to be a minor part.

Protein None

No protein or amino acids in the list.

Needs detergent to remove Yes

Water-insoluble silicones or waxes: a detergent wash is what removes them.

Hard-water defence None

No chelating agent in the list.

Fragrance Prominent

Fragrance sits in the first eight ingredients — a larger share of the formula.

Ingredients that matter

The ingredients that change a decision

The workhorse ingredients plus anything lower down that changes a decision. These chips name what an ingredient does — they are not safety scores, and no ingredient here is rated good or bad on its own.

IngredientWhat it doesWhy it mattersChip
Water solvent The base everything else is dissolved in Neutral
Behentrimonium Chloride conditioning agent Conditions and softens — this is what makes it comb through Detangles
Cetearyl Alcohol fatty alcohol Thickens and conditions — not a drying alcohol Softens
Fragrance fragrance The scent Fragrance
Dimethicone silicone A little smoothing and shine Buildup
Aleurites Moluccana (Kukui) Nut Extract botanical extract A trace plant extract Neutral
Gardenia Tahitensis Flower Extract botanical extract A trace plant extract Neutral

Dimethiconol Propylene Glycol humectant Adds a little water-binding Buildup
What the list leaves out, and what it carriesNo sulfates or drying alcohols. Protein-free: this is built for moisture rather than for strengthening. Contains fragrance. The silicones here need a detergent wash to come off.
Full ingredient list (20)

US labelling rules put ingredients above 1% in descending order of amount; below 1% they may be listed in any order. Annotations keep three readings separate: the ingredient's general function, its role in this product type, and what its position can support.

  • 1 Water
    General function

    The base of almost every rinse-off and cream hair product. It carries everything else and is normally the first ingredient on the label.

    Leading ingredient

    Listed in the first three ingredients, it is likely a structural part of this formula.

    • solvent
  • 2 Behentrimonium Chloride
    General function

    A positively charged conditioning agent that binds to damaged, negatively charged spots on the hair. It is the main detangling ingredient in most rinse-out conditioners.

    Leading ingredient

    Listed in the first three ingredients, it is likely a structural part of this formula.

    May suitDry, coarse, or high-porosity hair

    Electrokinetic measurement puts the C22 quat ahead of the C16 ones for deposition: the longer chain adds van der Waals stabilisation on top of the charge binding. That extra deposit is what coarse hair usually needs to comb through.

    May suitFrizz-prone, damaged, or high-friction hair

    A cationic conditioning agent: it binds to the damaged, negatively charged parts of the cuticle and lowers combing friction there.

    DependsBuild-up-sensitive routines

    Substantive by design. A routine with no detergent wash gives it nothing to leave with.

    International Journal of Cosmetic Science
    • conditioning agent
    • cleanser
  • 3 Cetearyl Alcohol
    General function

    A waxy fatty alcohol - nothing like drying alcohol. It gives conditioners their body and leaves a soft, smoothing film on the hair.

    Role in this product type

    In conditioner, cetearyl alcohol gives the emulsion its creamy structure and helps it spread evenly through the hair. Its emollient layer adds slip and a smoother feel.

    Leading ingredient

    Listed in the first three ingredients, it is likely a structural part of this formula.

    May suitDry, coarse, or high-porosity hair

    May suit dry, coarse, or high-porosity hair that benefits from added slip and a more substantial conditioning film.

    May suitFrizz-prone, damaged, or high-friction hair

    Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.

    DependsFine or easily flattened hair

    Consider if hair is fine or easily flattened: a formula built heavily around fatty alcohols can feel richer than a lightweight conditioner.

    • fatty alcohol
    • emollient
    • thickener
  • Below about this point, order stops being meaningful — these are typically used at 1% or less.
  • 4 Fragrance
    General function

    An undisclosed blend of scent ingredients. Regulations let it stay unlisted, so a fragrance-free product is the only way to be certain what is not in it.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May not suitFragrance-sensitive routines

    Declared fragrance. On a fragrance-sensitive routine this is the line that decides it, wherever it sits on the label.

    • fragrance
    • declared fragrance
  • 5 Dimethicone
    General function

    The most common conditioning silicone. It coats the strand for shine, slip, and frizz control, and needs a detergent (not just water) to wash out.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May suitClimate-sensitive or frizz-prone hair

    A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.

    May suitFrizz-prone, damaged, or high-friction hair

    Lays a smooth film along the cuticle, which lowers combing friction and flattens the surface irregularities that read as frizz.

    • silicone
    • emollient
    • conditioning agent
  • 6 Aleurites Moluccana (Kukui) Nut Extract
    General function

    An extract from the nut of Kukui (Aleurites Moluccana). Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    • botanical extract
  • 7 Gardenia Tahitensis Flower Extract
    General function

    An extract from the flower of Gardenia Tahitensis. Plant extracts are used across a wide range of levels, and label order is the best guide to how much is here.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    • botanical extract
  • 8 Cocos Nucifera (Coconut) Oil
    General function

    One of the few oils small enough to move into the strand, which is why it is used for pre-wash treatments. It can feel heavy or stiff on protein-sensitive hair.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May suitFrizz-prone, damaged, or high-friction hair

    A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

  • 9 Laminaria Digitata (Sea Kelp) Extract
    • botanical extract
  • 10 Musa Sapientum (Banana) Fruit Extract
    • botanical extract
  • 11 Mineral Oil
    General function

    A sealing oil that sits on the surface, adds slip and shine, and needs a detergent to remove.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May suitDry, coarse, or high-porosity hair

    Coats the surface and slows water leaving the strand, which is usually what coarse hair that dries out fast is missing.

    May suitFrizz-prone, damaged, or high-friction hair

    A thin oil layer lowers friction between strands and flattens the raised cuticle that scatters light and catches on its neighbours.

  • 12 Cetyl Alcohol
    General function

    A fatty alcohol used to thicken creams and add slip. It softens rather than dries.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May suitDry, coarse, or high-porosity hair

    The waxy solid that gives a conditioner its body. It deposits a soft lubricating layer, which is most of what makes hair feel smooth after rinsing.

    May suitFrizz-prone, damaged, or high-friction hair

    Deposits with the cationic conditioners and helps them lie flat along the strand, which is where the detangling actually comes from.

    PubChem
    • fatty alcohol
    • emollient
    • thickener
  • 13 Ethylhexyl Methoxycinnamate
    General function

    A UV filter added to protect the product's colour and, in leave-ins, to slow colour fade.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May suitGray, silver, or brass-prone hair

    Sunlight oxidises hair pigment, and on gray, silver or lightened hair that shows up as yellowing. A UV filter on the label absorbs some of the light that drives it.

    PubChem
    • UV filter
  • 14 Polyquaternium-37
    General function

    A thickening polymer that gives creams and curl products their bounce and helps them cling to the strand.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May suitCurls or waves needing flexible hold

    Cationic polymers hold a curl loosely and stay soft, which is why they turn up in definition products rather than firm-hold ones.

    May suitFrizz-prone, damaged, or high-friction hair

    A cationic polymer stays on the hair through rinsing, which is what keeps static and combing friction down after the wash.

    May suitMaximum-hold styling

    Film formers are what hold a style: they dry into a connected film across the strands so the shape resists movement.

    • conditioning agent
    • film former
    • polymer
    • thickener
  • 15 Propylene Glycol Dicaprylate/Dicaprate
    General function

    A light, dry-feeling ester that spreads other ingredients and softens without a greasy finish.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May suitFine or easily flattened hair

    A light emollient: it softens the surface with noticeably less weight than an oil or a butter.

    May suitFrizz-prone, damaged, or high-friction hair

    Spreads thin and lowers friction between strands without the heaviness of a fixed oil.

    • light ester
    • emollient
  • 16 PPG-1 Trideceth-6
    • emulsifier
    • solubilizer
  • 17 Cyclopentasiloxane
    General function

    A light, fast-evaporating silicone that spreads other ingredients then leaves. It gives serums their weightless glide.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May suitBuild-up-sensitive routines

    It leaves the hair by evaporating rather than by being washed off, so it is not part of what accumulates.

    May suitClimate-sensitive or frizz-prone hair

    A surface film slows how quickly humidity reaches the cortex, which is what limits swelling-driven frizz in damp air.

    May suitFine or easily flattened hair

    A cyclic silicone evaporates after it has spread the formula, so it carries the other ingredients without leaving weight behind.

    • silicone
    • emollient
  • 18 Dimethiconol Propylene Glycol
    • humectant
    • silicone
  • 19 Phenoxyethanol
    • preservative
  • 20 Ethylhexylglycerin
    General function

    A preservative booster that also adds a little softness. Almost always paired with phenoxyethanol.

    Estimated lower-concentration zone

    It appears around or below the estimated 1% line, where label order no longer indicates relative amount; its role may be minor or technical.

    May suitFrizz-prone, damaged, or high-friction hair

    Emollients fill and smooth the surface of the strand, which lowers the friction that lifts the cuticle and reads as roughness.

Sorted by price per ounce. Dated observations from our research, not live prices. Direct store pages, no affiliate links. We don’t sell this product.

How we work this out
  1. 10 oz is the size stores list most often; every comparison on this page is made at it. Other sizes are shown in the Sizes row and the store list.
  2. Commonly seen is the middle half of current prices for the 10 oz at recognised stores — the cheapest quarter and the dearest quarter are left out, so one sale or one overpriced listing can’t move it.
  3. Good value under $10 comes from the 8 products we score as doing the same job as this one. A quarter of them cost less than $0.98/oz; at 10 oz that is $10. Under that line you are paying less than most of them.
  4. About $13 is what those same products typically cost at this size — the midpoint of their prices per ounce, scaled to 10 oz.

Claims check

What the brand says, against what the formula shows

Claims are quoted from the brand. We only mark one supported, partly supported, or conflicting when the ingredient list actually speaks to it; everything else stays "stated by the brand", which is not a criticism — most claims simply cannot be read off a label.

How this page was made

  • Everything above is generated from our researched product record — identity, the ingredient list as printed, the brand's own claims, dated price observations, and review themes written in our researchers' own words. No part of this page is written per product.
  • The value band is a fixed label over two stored numbers: this product’s cost per ounce as a percentile of every product of this type we have priced, each at the size it is most often sold in, and how many products we score as doing the same job cost at least a quarter less per ounce.
  • Both scores out of ten are defined on this page. The formula score is completeness for the job, computed from a fixed per-format checklist shown beneath the gauge; the price score is cost per ounce against every product of this type we have priced.
  • The "Is this right for you?" panel reads only your own consultation answers, and it applies exactly the filters our recommendation engine applies. It is computed when you load the page and is never stored on it.
  • 5 sources consulted for this product (4 manufacturer or regulatory, 1 retailer, 0 editorial), last checked 2026-08-25.
  • Ingredient references are linked for 8 of 12 product-aware annotations on this page. Fit notes are conditional formulation guidance, not a conclusion about the finished product or about you.
  • We have not tested this product in a lab and we do not physically test your hair. Formula readings come from the ingredient list; behaviour claims are labelled as the brand's.
  • Ingredient order tells you relative amount only above roughly 1%. Prices are observations on the dates shown and change without notice.
  • Ingredient names link to our ingredient library, where each entry shows what it does, which product types use it, and where it usually sits on a label across everything we have researched.
  • This is cosmetic information, not medical advice, and nothing here diagnoses or treats a health condition.
  • Formula readings: derivation v22. Record last updated 2026-08-25.
